Application filed March 9, 1926.

This invention relates to a device for cleaning the teeth of a finetooth comb, and its object is to provide a device which is capable ofindefinite use, and which does not have certain defects present in theor dinary metal comb cleaners.

It will be understood by those skilled in the art that fine tooth combsa're provided with a series of exceedingly fine teeth, the

lo distances between each of the several teeth being so small that it isvery difficult to cut slots in a sheet of metal narrow enough to leave asufficiently solid tooth to be of' any effect in cleaning 4the comb sothat the only kind of -metal that can be used Jfor that purposesatisfactorily is a piece of wire which is usually drawn to give it thenecessary strength, and in the present instance a plurality of wires areused so that there is one wire for each space between the several teethin the comb, and the wire is suit-ably supported so that it is used intension and not as the teeth of the comb are used, so that it isadequate to remove any material that may adhere to the teeth.

An embodiment of the invention is shown in the accompanying drawings inwhich the same reference numeral is applied to the same portionthroughout the several figures of the drawings, and of which there maybe modifications Figure 1 is a longitudinal sectional view of one formof the comb,

Figure 2 is a transverse sectional view of the said comb,

Figure 3 is an illustration of the method of producing the cleaningwires used in the form of comb shown in Figure 1,

Figure 4 is a side elevation of a cheaper construction, and' Figure 5 isa transverse sectional view of the comb shown in Figure 4.

Figure 6 is a perspective view of a comb having teeth on only one sidethereof showing the cleaning wires substantially the same as those usedin Figure 1.

The comb back is indicated at 1, and it has the teeth 2 common to allfine teeth combs, This comb is slidable in a fiat rectangular case 3,which is open to provide a slot for the projection of the teeth from thecase. The back is provided with a slot at 4 Serial No. 93,363.

through which a pin 5 passes to enable the lever 6 to raise the combenough to clean the teeth of any adhering matter.

The lever 6 is pivoted to the top of the case at 7 and has a handle 8which lies 'down flat on the top of the case when the comb is ready tobe used. In order to provide for convenience in handling, the top of thecasing is provided with two small mouldings 9 and 10. A stop 8 preventsthe lever 8 from being lifted so high as to disengage the teeth 2 fromthe wires.

The cleaning device consists of a series of wires 11, which are securedto small plates 12 and 13 on opposite sides of the lower portion of thecomb casing. These wires are all arranged in a series of bars asillustrated in Figure 3 at 12 and 13, there being enough of the wires tocompletely cover the bars and they are arranged so that one wire passesbetween each pair of comb teeth. These strips carrying the wires arethen secured to the comb casing by soldering or otherwise, so that thewire passes through the spaces between the comb teeth and the comb islifted up and down from time to time to clean it with the lever 8.

In the form of the invention shown in Figures 4 and 5 there are two flatplates .20- 21 which plates are wound with a plurality of wires 22 whichpass through the spaces between the teeth of the comb and between edgesof the ordinary fine tooth comb, said teeth being indicated at 23 and24. i

The comb is long enough so that it projects from the casing formed bythe two plates 20 and 21, and said plates have knobs 25 and 26 thereonto aid in shifting the casing with respect to the comb.

In Figure 6 there is shown a comb having teeth 30, the comb back havingthe projectv ing notched ends 31 and 32 for operating it.

The comb cover consists of a strip of sheet metal folded upon. itself toform two portions 33 and 34 to each of which wire carrying strips 12 and13 may be secured the same as is shown in Figures 2 and 3. The wires 11then extend across the edges of the two plates 33 and 34 and between theteeth 30 of the comb.

Having thus described my invention, what parallel with said opening, andwires eX- tending from one bar to the other across send opening, andadapted to pass between the.

teeth of said comb7 and means of projecting said comb with the teeththereof outside of said frame to the limit of said cross wires.

In testimony whereof I have hereunto set my hand this 27th day ofFebruary A. D., 1926.
